2 Claims.

This invention relates to closures and, more particularly, to closuresfor bottles or jars or the like of the type commonly known as lug caps."

The chief object of my invention is to produce a closure of such typewhich islnexpensive to manufacture and forms a secure seal. An object ofmy invention is to produce a closure which may be readily applied tocontainers such as bottles or jars or the like and which may be easilyremoved and used again for reseal purposes, if desired. A further objectis to provide a "lug cap closure which is so constructed that itsexterior may be smooth or deformed or decorated as desired. A stillfurther object is to provide a closure in which the raw edge of theskirt is concealed to protect it against corrosion and to preventpossibility of injury to a user occasioned by careless handling of theclosure.

The invention relates to a closure for bottles or Jars or the likecomprising a cover portion, a skirt depending from said cover portionterminating in a raw edge, and a plurality of spaced inwardly rolledtabs or ears integral with said skirt and forming means for securing theclosure to a container, the terminal portion of said skirt betweenadjacent tabs being turned inwardly, upwardly and outwardly against theinterior of the skirt to conceal the raw edge, said rolled tabsextending radially inwardly from said skirt beyond the turned terminalportion thereof.

The attached drawing illustrates a preferred embodiment of my invention,in which Figure 1 is a sectional view of a shell from which the closureis formed;

Figure 2 is a sectional view of the closure; and

Figure 3 is a bottom plan view of the closure illustrated in Figure 2.

Referring to the drawing, there is shown a shell 2, formed of a singlepiece of metal, having a cover portion 3 and a skirt 4 depending fromsaid cover portion and terminating in a raw edge 5. The skirt 4 isprovided with a plurality of depending tabs 6 integral therewith andextending therefrom. Preferably, at least four of said tabs 6 in thespecific form illustrated are provided, spaced equidistantly about theskirt of wardly beaded lugs I are rolled to a greater diameter than thebead!) so that they extend radially inwardly from the skirt of the capbeyond the bead and consequently, are free to engage the thread of acontainer when the closure is applied thereto. Any preferred type ofliner may, of course, be employed.

The bead 9 presents substantially the same attractive rounded appearanceto the bottom of the closure as the inwardly, upwardly and outwardlyrolled lugs l as well as concealing the raw edge of the skirt therebyprotecting it against corrosion and obviating the possibility of injuryto a user occasioned by careless handling of the closure.

From the foregoing description of my invention, the many advantages ofthe closure can be the cap. The shells are fed to a machine, of a typewell known in the art, which turns the tabs 6 inwardly, upwardly andoutwardly to form rounded lugs l which act as means to secure theclosure to a container since they are adapted to engage a threadthereon. Simultaneously, the terminal portion 8 of the skirt 4 is turnedinwardly, upwardly and outwardly against the interior of the skirt inthe form of a bead 9, thereby concealing the raw edge 5. The rounded orinreadily perceived. The closure is inexpensive to manufacture since itmay be readily formed from a single piece of metal without the use ofexpensive machinery. The closure forms a secure seal and can be readilyapplied to and removed from containers, and may also be used for resealpurposes, if desired, since it is not necessary to break or deform itduring removal. The container engaging means of the closure are sodesigned and constructed as to be concealed from view thereby presentingan attractive appearance to the skirt of the closure.

While I have described and illustrated a preferred embodiment of myinvention, it will be understood it is not limited thereto but may beotherwise embodied within the scope of the following claims.

Iclaim:

1. A closure cap having a top and dependent skirt portion, a bead formedon the lower edge of said skirt portion on the inside thereof, said beadbeing undistorted for its entire length and of the same cross-sectionalshape and having portions of larger radii than other portions, saidportions of larger radii being adapted to engage suitable projections ona container without interrupting the continuity of the bead.

2. A closure cap having a dependent skirt portion formed with anintegral rolled-up continuous bead extending without interruption ordistortion completely around the edge of the skirt, said bead projectinginwardly from and concealed by the skirt portion, portions of said beadat spaced points being of less cross-sectional diameter than otherportions thereof and of less lateral projection toward the center of thecap than other portions, all portions of the bead being of likecross-sectional shape.
